Bending Residue Dihedral Analysis

Residue i Residue i+1 Distance of hinge axis to residue i in conformer 1 (A) Distance of hinge axis to residue i in conformer 2 (A) Change in psi (i) (deg) Change in phi (i+1) (deg) Angle of psi(i) axis to hinge axis conformer 1 (deg) Angle of psi(i) axis to hinge axis conformer 2 (deg) Percentage Progress  VAL-285   PHE-286  5.1 5.3 0.8 4.0 96.1 97.8 3.2  PHE-286   SER-287  3.3 3.2 0.8 -29.0 153.3 158.6 108.5  SER-287   PRO-288  3.6 3.8 1.3 -6.3 97.4 94.4 23.6 Graph shows rotational transition at bending residues and can be used to identify hinge bending residues. Probably only informative for interdomain rotations greater than 20 degrees
